Unfortunately not, to fix that you'd need to find the source of the leak and correct it
JP.

So what is the benefits of this fix?
Simply... Why we need this? Sorry but I didn't understand.... My bad mate

No problem The thing is, we have a certain amount of RAM at our disposal, plus our devices are getting faster and faster, getting more and more cores, but not that much RAM increase.
Let me illustrate my point :
htc HD2 (my frist device to run Android) - 2009
RAM : 448 MB usable
CPU : 1 GHz Qualcomm Snapdragon (single core)
SGS3 - 2012
RAM : 778 MB usable
CPU : 1.4 GHz quad-core Cortex-A9
So CPU speed is up by way much more than RAM, and I'm not taking GPU into consideration, plus storage speed increase etc...
Now those devices tend to be used in multitasking, having many apps running at the same time.
What those need is :
- CPU power to run on (we have plenty !)
- RAM to fit in (we have little)
Now even though an APP is running, not every bit of it is really needed, so those parts can be swapped out (put into swap) freeing these memory blocks and making room for more apps to fit in RAM.
So what will this mod do for you : Allow for more multitasking
Keep more apps running in RAM at the same time, making the device snappier when switching from one app to the other.
One app won't run faster !
If now you don't have swap, Android will have to gently ask the least used app to please close (save data, and quit) to free up RAM. Now when you get back to that app, Android will have to reload it, the app will start and reload it's data.
You can see, this will take more time.
Hope this isn't too confusing

I have a question before i attempt setting this up.
How do we identify which partition on the card is supposed to be for swap?
I have a 64gb sandisk card and say i make two partitions, one massive one for data and a 2gb one on the end for swap, how do i identify to android that the 2gb one is for swap? Also, what format should the partition be?
Cheers.

The script handles finding the partition
All you need to do is partition your card and be sure the swap partition is :
- a primary partition
- of type "Linux Swap"

I have 1gb micro sd card, so can i use whole card as swap card?

Yes, just create one partition with the size of the card, and make it a primary partition of type "Linux Swap".
But just a thought, what speed class is this card ? A too slow card might not be a good idea to use as swap device.
I'm waiting for my 64Gb card, so for now I'm running 512Mb swap on my older Transcend class 4 card, which is running fine for far. I'd not really go lower, though it's sur worth a try
JP.

Will the whole swap partition be used as swap memory?
And one more thing: what happens, if you remove the external sd, while the mod is active?

There's no mention what class it is. As i remember card came with some nokia phone 2-3 yerars ago, so i think that it's pretty slow, but i will test it anyway.

use with extsd and internal sd swap script?
Hi,
just wonder if I can use this with the extsd and interenal sd swap mod by mattiadj?
that will be great if i can use both mod and if we can use both, where will be the swap space? still the extsd?
thanks.

Hi,
Thank you for sharing this mod. What size would you recommend for the swap partition? I think that the general recommendation for desktop Linux is something like one to two times the size of physical RAM, depending on available disk space. Would that be reasonable for Android as well?

Swap will all be used, but they will have a priority (order) which you can check by typing "cat /proc/swaps" in a terminal.
I'd not use many though, you don't really need that much swap Just compare and keep whatever works best for you

On Android that might be shooting a little too high. I have a 512Mb partition, but I suppose 256Mb would be fine, that is the size I used on my previous devices.

Increase RAM??

ok so i was thinking our mini has 384mb ram of which only 280 are available...is there some way to use the whole RAM not only 280mb??
on froyo i had: 279mb ram
on ginger: 280
on ics: 276mb
so why not 384?? whats holding the other 104 mb?

think i found what i was looking for: "MemTotal" = physical memory minus whatever is being shared with devices (such as the radio, DMA buffers, etc), so it will always be less than the advertised RAM for your phone.
am i right??

Use swap it will increase your ram but you must have a good sd card.

you mean a class 10 card? If so, how do I create a swap partition for my rooted device?

It's because some memory is also used for graphics and other stuff. In ICS it is 279MB, but on JB it's 276 because I have increased framebuffer size for triple buffering etc.. Theoretically, by experimenting, it's possible to get at least 285-290MB.

Me, too..
I have experimenting and the result :
Froyo : 281 MB
Ginger : 279 MB
IceCream : 278 MB
JellyBean : 276 MB
as far as i know, RAM used by :
1. GPU
2. Graphics thing
3. And Other stuff..
Then the rest of them goes to RAM values, so your Mini RAM was around 300 Megabytes, but since GPU, and other things take it RAM just decreased.
I also have a Galaxy Tab 2 7.0 Inc, wich have a 1 Gigabytes RAM, but since other things take it, it decreased into 679 MB (wow, really huge decreased isn't it ? :silly: )

You can create a swap partition from cwm from advanced option then while partitioning SD card select a value for swap. This will completely erase your SD card so make a backup

Well, you can use a swap partition. CM7+ also has ram compression.

For me Ramexpander say is not compatible with Ace.

I heard swapping partition from sd card to increase the ram, sd card might get damaged!!, is it true?

Reduces SD Life so yes.
Sent from my iPhone

but i guess you will change your sd card before it gets damaged so much, that you will notice.
i only had this once on a USB pendrive. it loses data since some weeks ago. but its about 8 years old.
lets say that todays SD cards have better lifetime than years old USB sticks. lets also say that you use your sd card more often than i used this stick (backups later car-radio). so we can say your SD card might have a bit less lifetime. lets say 6 years. in 6 years you will (most likely) have a new phone, sd cards are "oldies" and if not, 1TB cards are state-of-the-art.
so....yes you loose lifetime but i dont think you will use it till it "dies"

It really depends on use. When I swapped i ate through my sdcard in less than 6 months.. so there you go. Keeping low swappinness will increase sd card life, but it does depend on use.

increasing ram by swapping sd card is effective to what extent...can any body tell me....does it bridge the gap of our low ram...

That why the requirement need class 10 SDcard

You can use CM7 that uses less RAM!.. I just went from CM10 to CM7 and it really is an improvement for ACE as it uses a bit less RAM and that is noticeable.

thanx but no cm7

there are quite a few apps for increasing the ram like ramexpander and swapper...
but before using these apps remember that the read and write speed of sd card(which is secondary storage) is vey less as compared to that of the internal ram.. and probably thats why ram is very expensive as compared to sd card...
so if you use these apps may take a bit longer to start and even the best of sd cards i.e. the class 10 one won't last longer than 6 months...

Increasing ram
Hi i install ram manager pro apk on gts5830i then i create a swap file 128mb using this apk, then on sd card i see swap file img does it mean my phone ram increased.... i didn't install any kernel for it... plz does tell me if it increase ram or not...

I tried something on a other phone from my neighbor. is a huawei with same specs than the galaxy ace..
I moved apps to SD card with link2SD and created a Swap file in the internal storage.
The internal storage is much faster than the SD card and much better for swap file.

What is RAM
Random Access Memory (RAM) is temporary data storage that the CPU uses during calculations. The more RAM a device has, the more calculated results the CPU can store - which means less time the CPU has to do the same thing over and over again. In other words, the CPU can check RAM to see if it has already made a particular calculation in the recent past. If it has, it can use the pre-computed results instead of wasting processing time recomputing the same calculation. In short, more RAM means a more efficient (and faster) device.
SWAP
What is SWAP
Swap is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.

More RAM?

Hi.
Does anyone knows how to swap sd card for expand ram to 4GB with stock rom or any rom. Is it possible on z3 compact. Samsung's phones can do this. Can we add more ram with storage on Z3Compact ?

Why do you need more RAM?

RAM and SD cards work at totally different speeds.
You could swap storage and SD card, but not RAM and SD card.

bookworth is right, the difference in speed between the internal memory and the sd card with make it go slower not faster.
You could use Kernel Audituor to increase the Z-RAM size, this will give you more page file on internal memory, but I doubt very much you'll see any difference in performance. Unless you're getting 'out of memory' errors, I'd leave it alone.

Even if you do that, there will be no performance gain. SD card is too slow for that purpose. Motorola did it the wrong way. They made a great device but didn't put in enough RAM to make it use its full potential.

You can use greenify and task killers to free up RAM. I know people say its not a good idea but it seriously works for this phone. It has too low RAM for Android to be able to handle it properly. It lags like hell without greenify and task killers.
